Just like the D•CURVE Piper, but smaller, to fit smaller faces. Blending style, function, and safety, D•CURVE Mini Piper BioTitanium sunglasses feature hypo-allergenic, medical-grade titanium frames for strength and flexibility, while maintaining light-as-a-feather feel. Our nylon lenses feature Nastek P3 Polarized technology, providing 100% UVA and UVB Protection. D•CURVE lenses also utilize a hydrophobic coating: resisting water, sand, dust, and oil - perfect for keeping your vision as sharp as your edges in rain, snow, or shine.
